To all whom t may concern:

Be it known that 1, HARRY SILLETT, a citizen of the United States, and a resident of Kansas City, in the cour-tyv of Jackson and State of Missouri, have invented certain new and useful Improvements in Hydrocarbon-Gas Generators and Burners, of which the'followin is a specification.

My invention 're ates to improvements in burners of crude oil and the like, and it consists in the constructions, combinations and arrangements herein described and claimed.

One of the foremost objects of the invention is to provide a burner system which comprises a hydro-carbon gas generator, burner, means whereby the crude oil which is employed may be instantaneously lighted, and an improved fuel tank including apart of the instantaneous lighting means.

A further object of the invention is to provide a multiple unit liquid fuel burner, embodying slide valve means whereby all of the units with the exception of one can be disconected so that only one burner need be used when thus required, with the result of effecting a saving in the consumption of fuel.

A further object of the invention is to provide a fuel oil burner which is capable of application to a stove l'insufficiently large to ermit of centralizing the burners under the ids, in which circumstance, the intake of the burner is projected and secured to the outside of the stove instead of the inside.

@ther objects and advantages will appeai` in the following specification, reference behad to the accompanying drawings, in

which Figure 1 isa diagram illustrating a double burner constructed in accordance with my invention, in connection with the improved fuel reservoir, more specifically described below,

Figure 2 is a detail side elevation of the improved burner structure,

or rib on the inside,

`Figure 8 is a detail cross section of the slide valve between the range and oven part of the gas range, and,

l general survey of the o eration ma b introduced at this time in oiider to familiar( ize the reader with the manner of starting the burner.. A pair of burners 1 are joined by a conduit 2, the right end of which has a curved cap 3 hereafter known as the intake.

Supported over the conduit 2 by means of plates 4, 1s a vaporizing pipe 5 which leads to the open end 6 of the intake 3, and is supplied by a suitable fuel oil from the reservoir .7 by means of a connecting pipe 8. This pipe 8 leads to one side of a valve body 9, Where-the flow of oil is controlled by means of a valve 10. There is a somewhat similar valve 11 on the other side of the valve body 9, this valve however, contrlliiig the flow of priming fluid from an aux-y iliary reservoir 12 inside of the main reserv'oir 7. A

A pipe 13 leads from the valve 11 to a U tube lft inside of the auxiliary reservoir. There 1s a pressure of air above the liquids in the reservoirs 7 and 12, as indicated by the presence of the gauge 15, and when the valve 16 is opened, some of the priming Huid 12, which is preferably gasoline, is forced out of the U tube 14, along the pipe 13, through valve 11 which was opened for the purpose, along vaporizing pipe 5 into the intake 3, thereafter escaping at the slots 17 .ofthe burners where the priming fluid 1s ignited and the vaporizing pipe 5 caused to be heated.

.After sufficient heating of the vaporizing pipe 5, the priming valves' 11 and 16 are closed and the fuel valves 18 and 10 opened. It should be observed that there is a minute orifice 19 at the bottom of the U tube 14, for the purpose of admitting the priming fluid. Air enters the open end of the U tube, picking up the fluid in sufficient quantity to -make a rich gas.

means of pressure in the reservoir 7, and when this oil reaches the vaporizing pipe 5, it is turned into hydro-carbon gas by reason of the action of the heat thereon, the gas then entering the intake 3to be subsequently consumed at the places where it escapes out of the slots around the burners. Air mingles with the gas'at the opening 6 of the intake 3, as can be plainly seen in Figure 3.

The burner structure comprises two or more burner rings, as illustrated in Figure 1. The conduit section of each ring is flanged as 2O at the ends, for the purpose of securing the burner parts together in the middle and to secure a mounting for the supporting plates 4 which carry the vaporizing pipe. These mounting plates 4 provide convenient means for fixing the burner to a stove in cases where the stove is not large enough to fully accommodate the burner. ln such cases, instead of fixing the burner on the inside. the ends thereof are projected out of the sides or rather ends of the stove, whereupon the mounting plates 4 are made use of to boltor otherwise secure the burner structure to the outside of the stove.

One of the intermediate flanges is recessed at 21 to admit the slide 22 which is used for the purpose of cutting out or disconnecting the back burner 1 at the left in Figure l, should it be desired to employ only the-burner at the right. This provision is one of convenience and economy. since in cases where it is desired to use only one burner it naturally follows that there is a lesser consumption of fuel..

Adjustments of the flow of gas out of the nozzle 23 are made by means of the needle valve 24. A rib 25, shown in Figure 5, runs lengthwise of the conduit 2 for the purpose of strengthening the burner structure so that there may be no undue sagging. A further detail of construction consists in ribbing the under side of the stove lid 26 in Figure 9 for the purpose of strengthening the lid and preventing it from warping by the effect of the flame from the burners,

but move particularly to facilitate heat radiation.

The gas oven structure 1s shown particularly in Figures 6 and 7 wherein it is to bev observed that the same burner structure, shown in Figure 1, is employed, all similar reference characters indicating lie parts. rlfhe slide valves between the various burner vsets have rods 27 leading` to the outside of completely shut oil' by means of the slide valves 30, so that either very little air will be drawn in with hydro-carbon gas, or the burners will have to depend for their air supply from that which is normally present in the compartment.

The oven 31 is jacket-ed at 32, the passa e of heat from the burner structure in t e oven being as indicated by' the arrows, the products of combustion finally escaping at the Hue 33. Should it be found that the heat is too great for the oven, the large slide valve 34 in 'the back 35 of the oven, can be opened so that part of the heat passes directly into the stove compartment and from thence out of the flue 33, instead of passing around the oven 31 as just stated and as indicated by the drawing.

A hinge connection 36 permits of swinging the oven down into the dotted line position in Figurelf, in cases where it is not desired to use the oven or when it is desired to obtain access to the burner structure for cleaning vand adjustments. The, oven burners are mounted in precisely the same manner as are the stove burners, there being a separate compartment 29a at the upper end in Figure 6, .for the l the intake 3. There is also a slide or gate valve a for the purpose of regulating the admission of fresh air.

While the construction and arrangement of the improved hydo-carbon gas burner as herein described and claimed is that of a generally perferred lform, obviously modifications and changes can be made` without departing from the spirit of the invention or the scope of the claims.l
